AUTOMATIC CARBURETOR CONTROL.

I Application filed June 1,

To all whom it may concern:

which the following is a specification.

This invention relates to carburetors, and more particularly to a thermostatically controlled regulating means employed in connection with the gas valve of a carburetor for adjusting the supply of fuel to the caruretor according to the heat of the engme.

A further object of the invention is to provide a device ofthis character which may be readily and easily applied to motors now in use. it being unnecessary to alter the construction of the motor to accomplish the positioning of the device.

Vith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the lnvention herein'disclosed. may be made within the scope of what is claimed, withpnt departing from the spirit of the invenion.

Referring to the drawing Figure 1 is an elevation of a. device constructed in accordance with the present invention, an engine manifold and carburetor being indicated in dotted lines.

igure 2 is a sectional view taken on line 2-2 of Figure 1.

eferring to the drawing in detail, the

reference character 5 designates a sleeve or collar to be secured to the exhaust manifold of an internal combustion engine, the manifold in the present drawing being shown in clottedlines, and being indicated by thereference character 6.

A bar 7 has its upper extremity pivotally connected with the sleeve or collar 5 as through the screw 8, the bar 7 being however formed of suitable spring'material to cause a pressure to be'exerted at the lower extremity thereof, resulting in the gear 9 carried thereby, being'forc'ed into engagement with the pinion 10. r

- The pinion 10 is secured to the valve stem 11 to move therewith so that movement of Specification of Letters Patent.

the bar. 7 laterally, will result in a relative movement of the valve stem 11 to'accomplish the adjusting of the valve carrier at the lower end thereof.

Associated with. the bar 7 is a bar -12 which has one end thereof pivotally connected with the bar? at a point in spaced relation with the upper end thereof, the connection being made through the pin 13. The opposite end of the bar 12 is secured to the manifold G, as at 14, to the end that when the manifold 6 becomes heated, the bar 12 will also become heated causing the same to expand, which expansion causes the bar 12 to move.

Patented June 20,1922.

' It follows that since one end of the bar 12 is bar 12 moves the greater quantity of fuel to the carburetor.

aving thus described the invention, what is claimed as new is 1. In combination with the exhaust manifold and carburetor of an internal combus tion engine, a pivoted bar supported by the exhaust manifold. a bar having connection with the pivoted barand adapted to move with the expansion of the manifold, and means for connecting the first mentioned bar and valve of the carburetor, whereby movement of the pivoted bar results in a relative movement of the valve member.

2. In combination with the exhaust manifold, gas regulating valve of a carburetor of an internal combustion engine, a. pinion carried by the valve, av pivoted bar having connection with the exhaust manifold and carrying a gear in mesh with the pinion, and a bar having connection with the pivoted bar and adapted to move with the expansion and contraction of the manifold to accomplish the adjusting of the valve.
